Other Parts Discussed in Thread: SEGGER, TM4C1294NCPDT, UNIFLASH
Hello,
The EK-TM4C1294XL, connected to a custom EPI adapter card, had been running successfully.
With the adapter card card installed it had been CSS/LM programmed multiple times.
Problems with the arrangement developed so the adapter card was removed to test the EK-TM4C1294XL in stand alone mode
CSS was no longer able to program the EK-TM4C1294XL.
The original program running on the EK-TM4C1294XL permitted LM command line Ethernet programming which continued to work.
Using the Ethernet method, TI's gpio_jtag program was loaded and verified running through the COM port. It showed "Pins are JTAG".
Both CSS and LM were unable to program the EK-TM4C1294XL but were able to program other EK-TM4C1294XLs.
Signal capture shows no activity on TDO on the problem EK-TM4C1294XL but activity on the other EK-TM4C1294XLs.
Obviously no activity on the TDO is symptomatic. LM is not able to retrieve "Current Values"
If the gpio_jtag program is running showing "Pins are JTAG" why is it not possible to CSS/LM program the EK-TM4C1294XL?
LM Flash Programmer Build 1613
Thanks for your help,
Victor
